The Centipede will attack in 12 waves. In the first wave, the Centipede will have a head attached to 11 body segments. In the second wave, the Centipede will have a head attached to 10 body segments, in addition to a detached head. The third wave will have the Centipede with an attached head, 9 body segments, plus two detached heads. These body segments will transform into heads and continue to do so until Wave 12. In the last wave, the Centipede will have 12 detached heads, independently attacking the player. Centipede heads are worth more points than body segments.
Attacks from the Centipede will come from the top of the screen, moving downward. If a spark hits any part of the Centipede, that particular body segment will transform into a mushroom, while the body segment behind it will become the new Centipede head. When the Centipede is destroyed, it will briefly disappear and re-appear from the top of the screen again.
